Roller press and high pressure roller mill combination set roller shaft

Abstract

The invention discloses a roller shaft combined with a roller press and a high-pressure roller mill, and relates to a roller shaft of a roller press and a high-pressure roller mill, including a shaft core and a shaft sleeve, and the shaft sleeves are at least two The combination sleeve is arranged and combined along the axial direction. The invention is a roller press and a high-pressure roller mill that are less difficult to manufacture, can effectively guarantee product quality, have interchangeability between different models, have a short production cycle, and can realize serialization, modularization, and large-scale production. Squeeze roller shaft.

Description

technical field [0001] The invention relates to a squeeze roller shaft of a roller press (or called a high-pressure roller mill). Background technique [0002] With the development of grinding technology in recent years, the roller press (or high-pressure roller mill) based on the principle of material bed grinding has been widely used in cement clinker, cement raw meal, slag, steel slag, iron ore, chemical and other powders. In the field of grinding, obvious energy saving effect has been achieved. However, with the widespread application of roller presses (or high-pressure roller mills) and the serialization of specifications, especially after large-scale, the extrusion roller shafts of traditional roller presses (or high-pressure roller mills) will face the following question: [0003] 1. It is very difficult to make large-scale roller shafts. The extrusion rollers of large-scale roller presses (or high-pressure roller mills) can weigh up to 60-70 tons, have a diameter o...

AI Technical Summary

Problems solved by technology

[0003] 1. It is very difficult to make large-scale roller shafts. The extrusion rollers of large-scale roller presses (or high-pressure roller mills) can weigh up to 60-70 tons, have a diameter of up to 2.4 meters, and a length of up to 5 meters. Forging or Casting production equipment and process requirements are relatively high

[0004] 2. It is difficult to guarantee the product quality of large rollers. When the production equipment and process of rollers are difficult to guarantee, the quality of products is difficult to be stable. As the core component, the shaft bears very harsh loads and working conditions. If there is a quality problem with it, it is likely to cause serious accidents, resulting in heavy personal and property losses

[0005] 3. Due to different application fields and output requirements, there are many types and sizes of extrusion rollers of roller presses (or high-pressure roller mills), which lead to a large amount of investment in production preparation materials such as molds in the early stage

But it is a whole set, and it also faces the problems of manufacturing difficulty and product quality in the production of large-scale models; and there is no interchangeability between different models, the production cycle is long, and serialization, modularization and large-scale production cannot be realized
